RESUMO
Objective: to determine the simultaneous presence of H. pylori in both the oral cavity and gastric mucosal in patientssuffering digestive pathologies and to establish the possible association between the presence of H. pylori inthe oral cavity and the gingivoperiodontal pathology. Study design: Patients with gastric symptoms (case group)and asymptomatic patients (control group) seen at the Gastroenterology Department of Dr. Julio C. Perrando Hospital(Resistencia, Argentina) were selected. Dental plaque and saliva samples from both groups were obtained. Inthe case group, gastric biopsy samples were also taken. H. pylori was detected in gastric biopsies by histologicalstains, and Polymerase Chain Reaction (PCR) was carried out on the oral samples. Results: Among the 98 patients(43 cases and 55 controls), 196 oral samples (saliva 98, dental plaque 98) and 43 gastric biopsias were obtained.H. pylori was detected in oral samples in 18/98 patients, in gastric biopsies in 38/43 patients, and in both samplesin 15/43 patients. Conclusions: The presence of H. pylori in the oral cavity of patients suffering digestive pathologiesis more frequent in those patients harbouring a gingivoperiodontal disease, and this fact could represent anobstacle for the eradication of the bacterium. At the same time, it could constitute a risk factor for gastrointestinalreinfection after treatment (AU)
